Great work; I always thought it was kind of lame that Mega Satan uses the same music. This track should have been vanilla, tbh

heres a link to the song since the one the creator used is private https://www.youtube.com/watch?v=8ZII5lRnbWc

The base API doesn't allow for this but REPENTOGON should allow for that.

Hello. I wonder if it is feasible to implement a BGM replacement for Mother (Broken Heart)? The traditional Antibirth music replacement mod is to replace the original bgm, which causes the bgm to start playing after the end of the Isaac vs. Mother scene, but Antibirth should play the bgm as soon as the scene appears, which is too much of a violation.

Working in rep

How about integrating a Jukebox compatibility?

Repentance compatibility?

the video is private

Imma check it out, Thanks!

#modding-dev @ https://discord.gg/isaac is a good resource for this

Hello!

I am in need of help on how to do stuff like this, as I'm trying to do something similar, like trying to replace a certain file of music with something else (For example: only changing the music that plays when you fight a sin boss, instead of changing the challenge room theme as well).

I would appreciate some help, as I've tried to do this myself, only for it to fail and not change a thing.

If you have any tips on how to do this, please! reach out to me!

Might need a new video.

This mod might be pretty old, but apparently it's still used a lot nowadays, I guessed it would be a good idea to share an optimized version of your code so you can update if you want.

---- Code

local mega_satan_music = RegisterMod("Unique Mega Satan Music", 1)
local mManager = MusicManager()
local CustomMegaSatanTrack = Isaac.GetMusicIdByName("Mega Satan Fight")

mega_satan_music:AddCallback(ModCallbacks.MC_NPC_UPDATE, function()
if mManager:GetCurrentMusicID() ~= Music.MUSIC_SATAN_BOSS then return end

mManager:Play(CustomMegaSatanTrack, 0.1)
mManager:UpdateVolume()
end, EntityType.ENTITY_MEGA_SATAN)

could you make a mod that changes mega satans music to Enmity Of The Dark Lord (the originla theme from the original game)

1.25x speed also works, too

Thank you very much. The lack of a custom theme has been bugging me for a long time.

Like void music

The song its called $atan 666 and its an Bonus track of the Binding of Isaac Rebirth, if you buy the OST paying 6.66 dollars you got the extra song

how did you find out

Approved By Isaac's Mum BTW

Amazing

This music is reallty good

It's the same music that has found good communication. Doom - like atmosphere

cool music like like like thanks

@the7screw
Between this one and the regular "Regicide", it fits more to MS ... The regular one are too quick with his attacks for the slowness of this music at the contrary of Mega Satan, much slower

good mod

good music

sounds like it would fit the normal Satan fight (hint hint)
